## 🚀 Getting Started

### Option 1: Docker Deployment (Recommended) 🐳

> The easiest way to get started!

```bash
# Clone the repository
git clone --depth 1 https://github.com/ystemsrx/mini-nanoGPT.git
cd mini-nanoGPT

# Start with Docker Compose (recommended)
docker-compose up --build

# Or build and run manually
docker build -t mini-nanogpt .
docker run --gpus all -p 7860:7860 -v $(pwd)/data:/app/data mini-nanogpt
```

This will automatically build the Docker image and run the container. The container will detect your system environment (CPU/GPU) automatically. The `data`, `models`, and `assets` directories in the current working directory will be mounted into the container.

🌐 Once started, visit **http://localhost:7860** to access the application.

For more details, please refer to [Docker Setup](docker/README.md).

---

### Option 2: Local Installation

```bash
# Clone the repository
git clone --depth 1 https://github.com/ystemsrx/mini-nanoGPT.git
cd mini-nanoGPT

# Install dependencies (Python 3.7+)
pip install -r requirements.txt

# Launch the app
python app.py
```

Open **http://localhost:7860** in your browser to see the training interface!

## 🎮 User Guide

### Step 1: Prepare Data

Navigate to the **"Data Processing"** page, paste your training text, and choose a tokenization method.

> [!TIP]
> - For better results, enable the tokenizer option — it will automatically build a vocabulary based on your text
> - If you don't want to use a validation set, check the "Skip validation set" option

Click **"Start Processing"** when you're done.

#### Supported Data Formats

You can provide training data in multiple ways:

| Method | Description |
|--------|-------------|
| **Direct Input** | Paste text directly into the text box |
| **Directory Input** | Specify a directory path containing your data files |

**Directory Mode** supports **recursive scanning** of all subdirectories and the following file formats:

- **`.txt`** — Plain text files (entire file as one document)
- **`.jsonl`** — JSON Lines format with `{"text": "..."}` structure

<details>
<summary>📝 JSONL Format Example</summary>

```jsonl
{"text": "This is the first document content."}
{"text": "This is the second document content."}
{"text": "Each line is treated as a separate document with EOT token appended."}
```

</details>

> [!NOTE]
> When using directory input, files of different formats (.txt and .jsonl) can be mixed in the same directory structure. All files will be processed correctly.

### Step 2: Train the Model

Switch to the **"Training"** page and adjust the parameters as needed (or leave them as default for a quick try).

- **Loss Curves**: Blue = Training Loss, Orange = Validation Loss
- If only one curve appears, check the terminal for block size errors — try reducing it to 128

</details>

> [!NOTE]
> **Evaluation Mode Only?**  
> Set the `Number of Evaluation Seeds` to any value > 0 to activate evaluation-only mode. You'll see how the model performs with different random seeds.

---

### Step 3: Generate Text

Go to the **"Inference"** page, enter a prompt, and click **"Generate"** to see what the model comes up with!

### Step 4: SFT Training (Fine-Tuning) 🆕

The **Supervised Fine-Tuning (SFT)** feature allows you to fine-tune pre-trained models for conversational AI tasks.

#### How to Use SFT:

1. Navigate to the **"SFT"** page
2. Select a pre-trained base model from your model database
3. Import your dataset in **Alpaca format** (JSON file or directory)
4. Configure training parameters (learning rate, epochs, etc.)
5. Click **"Start Training"** to begin fine-tuning

<details>
<summary>📸 View SFT Training Screenshot</summary>
 
<img src="assets/imgs/en_sft.png" alt="SFT Training" width="100%"/>
</details>

#### Alpaca Dataset Format:

```json
[
  {
    "instruction": "What is the capital of France?",
    "input": "",
    "output": "The capital of France is Paris."
  },
  {
    "instruction": "Translate the following to Spanish:",
    "input": "Hello, how are you?",
    "output": "Hola, ¿cómo estás?"
  }
]
```

#### Chat with SFT Models:

After SFT training, go to the **"Inference"** page to have interactive conversations with your fine-tuned model!

</details>

---

### Step 5: Model Comparison

Navigate to the **"Comparison"** page to compare two models side by side:

- Select two models (they can even be the same model with different settings)
- Their configurations will be displayed automatically
- Input the same prompt to see how both models generate text
- Compare outputs with different inference settings (temperature, top_k, etc.)
